With 10 hours between them, Los Angeles and Istanbul have no overlap during standard business hours — by the time one team logs on, the other has logged off. The usual fix is an early start for Los Angeles or a late finish for Istanbul — pick whichever team has more flexibility. One seasonal catch: Los Angeles springs forward and falls back, but Istanbul doesn't, so the gap changes by an hour for several months of the year.
